Classification
Fadenia belongs to Eugeneodontida, an extinct order of Chondrichthyes that are characterized by the presence of tooth whorls. Fadenia is one of the few eugeneodont genera that survived the end-Permian mass extinction event, and it was one of the latest-surviving members of this clade. It could reach about 1.5 m in length.
